facebook api / sdk v4

Currently i am trying this and i am getting the following error

function facebook_sm(){
require_once( 'Facebook/FacebookSession.php' );
require_once( 'Facebook/FacebookRedirectLoginHelper.php' );
require_once( 'Facebook/FacebookRequest.php' );
require_once( 'Facebook/FacebookResponse.php' );
require_once( 'Facebook/FacebookSDKException.php' );
require_once( 'Facebook/FacebookRequestException.php' );
require_once( 'Facebook/FacebookAuthorizationException.php' );
require_once( 'Facebook/GraphObject.php' );
 
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;

// init app with app id and secret
FacebookSession::setDefaultApplication( 'xxx','yyy' );


}

Select allOpen in new window

error:

Parse error: syntax error, unexpected 'use' (T_USE) in /home/content/21/10892721/html/bushbase/system/includes/functions_social.php on line 999

line 999:

use Facebook\FacebookSession;

if i remove

use Facebook\FacebookSession;
	use Facebook\FacebookRedirectLoginHelper;
	use Facebook\FacebookRequest;
	use Facebook\FacebookResponse;
	use Facebook\FacebookSDKException;
	use Facebook\FacebookRequestException;
	use Facebook\FacebookOtherException;
	use Facebook\FacebookAuthorizationException;
	use Facebook\GraphObject;
	use Facebook\GraphSessionInfo;

Select allOpen in new window

i do not get the error and then if i try and call the classes like so

$conn= new FacebookSession('xxx','yyy');

i get an error that the class does not exist

i look on the library that has class FacebookSession documented and there are errors in the script (may just be dreamweaver)

if i remove the namespace line in the scripts and run my function again i get the following as the conn var

FacebookSession Object
(
    [token:FacebookSession:private] => 468805886582817
    [signedRequestData:FacebookSession:private] => 277ffb54d927326812fdc93213dc4dfd
)

Select allOpen in new window

i no longer get any errors regarding the namespace

moving on i then try and get the profile using:

$user_profile = new FacebookRequest($conn, 'GET', '/me');
		$user_profile->execute()->getGraphObject(GraphUser::className());
		echo'<pre>';
		print_r($user_profile);

Select allOpen in new window

running this code i get the following error

Fatal error: Uncaught exception 'FacebookAuthorizationException' with message 'Invalid OAuth access token.' in /home/content/21/10892721/html/bushbase/system/libraries/facebook/FacebookRequestException.php:104 Stack trace: #0 /home/content/21/10892721/html/bushbase/system/libraries/facebook/FacebookRequest.php(291): FacebookRequestException::create('{"error":{"mess...', Object(stdClass), 400) #1 /home/content/21/10892721/html/bushbase/system/includes/functions_social.php(1086): FacebookRequest->execute() #2 /home/content/21/10892721/html/bushbase/system/socialmedia.php(111): facebook_sm() #3 {main} thrown in /home/content/21/10892721/html/bushbase/system/libraries/facebook/FacebookRequestException.php on line 104

any help is greatly appreciated

Did you create an app on facebook yet?  https://developers.facebook.com/   Apps > Create New App  

Get your credentials.  

It has been a while since I have updated any of my facebook apps. They keep changing and I stopped trying to keep things up to date.  But I think this has been answered here already.  See if the thread below helps.  Most important thing is to create your app on facebook first and get your credentials and set up permissions for the app on facebook first.   Just doing that solves most issues.

This is only one piece of the puzzle (and it's a big research project).  It applies to the parse error in the first code snippet.

Please see this link, perhaps downvoted because the PHP comments are not supposed to be taken for pedestrian matters such as parse errors.  That said, it seems to identify the issue with use inside a function definition.

Hi,

i think it is best to deal with facebook using cURL and http referrals instead of their SDK. ive had soo many issues with it that i dont think its worth diving into

thanks

Wow, a grade of "C" -- what did we do wrong here?  I think the E-E Grading Guidelines expect anyone to explain a grade like that.

Hi,
My reasoning is as follows:
1.  Took approx a month to get an response
2.  Padas response was something a work around and not specifically what i was looking for - i was already using http
3.  Ray you pointed me in another direction for more information which was somewhat useful
4. eventually, i came up with my own solution based on my own research
5. i though that both of you should be rewarded for your work but didnt help me come up with a solution ( i did it in the month that it took for the question to be answered and waited to see if the experts could come up with something i didnt see).

 i think based on my explanation the score is fair

A grade of "C" is inappropriate, especially when you've asked a question that requires a lot of research and has a lot of moving parts.

i came up with my own solution

The right thing to do is post your own solution and accept that as the answer.  Then anyone visiting in the future will gain the benefit of your research.

Hi,

I created a new question to attack another area of the above question

i posted my solution in the top question part
